xPos

Horizontal position, expressed in pixels respect to the client area of the whole user interface of the waveform analyzer, where the mouse generated the notification

yPos

Vertical position, expressed in pixels respect to the client area of the whole user interface of the waveform analyzer, where the mouse generated the notification

nPressPosInPix

Number representing the position expressed in pixels where the mouse button was pressed. If the mouse action should have been performed outside of the waveform's area, this parameter would be set to -1.

It's important to note that this parameter doesn't represent the horizontal position on the waveform's visible area (for this you can refer to the xPos parameter) but to the horizontal position in pixels calculated respect to the bitmap representation of the total waveform's width in pixels at the current horizontal zoom factor.

nPressPosInMs

Number representing the position expressed in milliseconds where the mouse button was pressed. If the mouse action should have been performed outside of the waveform's area, this parameter would be set to -1.
